EDWIN CHAR-LES JONES, OF TORONTO, ONTARIO, CANADA, ASSIGNOR OF ONE-HALF TO JAMES PEARSON, 0F TORONTO, ONTARIO, CANADA.

GAS-HEATER.

To all whom it may concern:

Be it known that I, EDWIN CHARLES J ONES, of the city of Toronto, in the county of York and Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Gas-Heaters; and I hereby declare that the following is a full, clear, and exact description of the same.

My invention relates :(a) to the peculiar construction of the bottom of the heater casing and the burner and their arrangement to each other for the formation of an air chamber between them, into which atmospheric air is delivered to be battled by the burner and directed laterally for an even distribution to the burner outlets for the complete oxidation of the gas and the creation of non-luminous flames thereby; (7)) to the peculiar construction and formation of the heat distributers and the supporting grate therefor which form with the burner, a combustion chamber whereby the unburnt gas from the burner outlets may be consumed before coming into contact with the heat distributers.

For an understanding of my invention, reference is to be had to the following description and to the accompanying drawings, in which Figure 1, is a broken elevation, partly in section, showing the relative location and arrangement of the parts; Fig. 2, is a broken plan view looking at the top of Fig. l; and, Fig. 3, is a vertical section through the heater shown in Fig. 1.

Like characters of reference refer to like parts throughout the specification and drawings.

As the bottom (Z of the heater casing a is peculiarly constructed to maintain the delivery of atmospheric air to the burner e, I will specifically describe the structural character of this feature.

The central part of the bottom (Z is convexed, as shown at d in Fig. 1, and this convexed part (Z is provided with apertures d within the perimeter of the burner 6, through which the atmospheric air enters for the oxidation of the hydrocarbon gas emitted through the gas outlets e.

The burner is of a hollow formation and imperforate, except as regards the gas outlets e which are arranged around the rim of the burner, and is supported at a suitable height above the casing bottom 03 to form an Specification of Letters Patent.

air chamber f between the burner bottom 6 and the convexed part (5 of the casing bottom (Z, and in order that the air chamber f may be of uniform dimension, the curvature of the concavity in the burner bottom 6" corresponds with the curvature of the convexity of the part (Z.

As shown in the drawings, the apertures cl are within the line of the perimeter of the burner e and the atmospheric air admitted through the apertures d is delivered into the air chamber f between the burner bottom and easing bottom, the burner bottom acting as a battle to prevent the further upward course of the air in the line of admission, and to direct it laterally in all directions beyond the perimeter of the burner 6, this lateral distribution of the air providing a sutlicient and even supply of oxygen to all of the gas outlets e for oxidizing the gas emitted therefrom, and creating a non-luminous flame completely around the burner, which flame is the manifestation of complete combustion.

To rigidly support the burner 6 above the casing bottom (Z without imposing any strain upon the construction of the heater and particularly on the casing bottom, I have provided the burner 6 with a gas inlet pipe 9 preferably supported from below the heater, and have formed in the casing bottom (Z a suitable aperture for the gas inlet pipe to extend through the casing bottom into the heater.

Fitted on the gas inlet pipe 9 is an igniter z' to effect the ignition of the gas emitted through the gas outlets e of the burner c, this igniter 2' being preferably actuated by a rod j moved by the turning of the lever k when actuated to turn on the gas supply. The top of the burner e is preferably provided with a standard Z to support a 0011- cavo-convex grate m, on which is placed refractory heat distributers 0. The grate m and the heat distributers 0, by means of the standard Z, are suitably supported to form a combustion chamber 7 above the burner e to permit of the complete combustion of the gas before the flames from the gas, emitted through the gas outlets e come into contact with either the grate or the refractory heat distributers. In this way, the complete oxidation of the hydrogen and the incandescence of the carbon is effected, and these elements are converted into heat which is absorbed by the grate and the refractory material thereon.

A heater constructed in accordance with this invention will completely destroy the carbon in the gas, a. 6., it will, by converting it into carbon dioxid, CO eliminate the free carbon in the gas-the complete combustion of the gas being essential, (a) for economic reasons; and (b) for cleanliness.

The action of the invention thus far is as follows :-The lever is is operated to turn on the gas, which immediately flows through the gas inlet pipe 9 to the burner e.

The ignition of the gas heats the distributers 0, which in turn radiate the heat evenly to all parts of the casing a, from which the heat is diffused to the surrounding atmosphere. The burnt gas from the burner and its related parts ascends through the heater to the burnt-gas flue or flues u, from which it passes into the hollow cover 1', to escape through the outlet flue g.

Having thus rully described the nature of my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a gas heater, the combination of a heater casing having a convexed bottom, a burner supported above the convexed bottom of the heater casing, the bottom of said burner being concaved to correspond with the convexity of the bottom of the heater casing whereby they form between them an air chamber, said bottom of the heater casing having perforations within the line of the perimeter of the burner for the admission of atmospheric air to be baflied by the burner bottom, a gas supply connected with the burner and means for controlling the flow of gas to the burner.

2. In a. gas heater, the combination of a heater casing having a convexed bottom, a burner supported above the convexed bottom of the heater casing, the bottom of said burner being concaved to correspond with the convexity of the bottom of the heater casing, whereby they form between them an air chamber, said bottom of the heater casing having perforations within the line of the perimeter of the burner ror the admission of atmospheric air to be baflied by the burner bottom, a gas supply connected with the burner, a concavo convex grate supported above the burner to form below it a combustion chamber, and refractory heat distributers supported on said grate.

8. In a gas heater, the combination of a burner, a concavo convex reticulated grate supported above and separated from the burner to form with it a combustion chamber for the consumption of the unburned gases from the burner, and refractory heat clistributers supported on said grate for the absorption and distribution of the heat units from the burnt gases at the burner.
